Patented Oct. 18, 1932 PATENT o FF'IcE AINsWoR'rI-I BUCK, or YEAVSTORANGE, NEW JERSEY SA: FETY ANCHOR 5 Application filed January 9, 1930.Serial No. 419,?26.'

The invention relates in general to a window cleaners safety anchor andto the combinationof the same with a multiple part building constructionunit suchas a window casing. Y

It is a usual practice in mounting anchors of this type in position toextend them more or less into the masonry and similar structural partsin order to insure a security ofconnection. Under some circumstances itis diificult, if not impossible, to' drill into old masonrystructures'in order to mount the an fehors'in place and under othercircumstances it is dificult to attain sufficient purchase on themasonry structure to efiect a positive securing of the anchor in thedesired place. To meet this difficulty it has been suggested to securethe anchor to'an exposed element of the window frame or other structuralunit distinct from the masonry but this face mounting of the anchor hasnot been a'safe procedure as abnormal strain on the anchorv would be;very apt to either break theanchor away from the frame or carry with itthe particular portion of the frame to which it was attached. Ithas alsobeen suggested to pass the anchor through several: window frame partsand then in order to prevent any tendency of this form'of' anchor torotate to provide prongs which are designed to be driven into the faceportion of wooden frames. Such structure isof no value in' the case offrames otherthan wood or where for any reason it is not desirous'tomutilate the wooden face and further a different size anchor'has tobe-providedfor frames'or similar and the like, without necessityofumutilating exposed surfaces; which will securely position the anchorin place with a single fastening bolt which can be accommodated toframes of diiferent depths simply by selecting the proper size of boltand which will tend additionally-to secure together the'parts of theframe structurejto which it is attached and thus minimize the tendencyto separate the parts of the same or other structure to which it isattached.

Another object of the inventiomand' speci- 55 fically'referring to theanchor as an article of manufacture per se, is to provide for maximumstrength and rigidity with the use of theleast possible amount of metaland to dispose the metal in such way as to cause one 50 part to bracethe other and to provide a rugged form of harness engaging post whichwill facilitate an easy engagement therewith of the harness and whichwill tend to brace the supporting portion of the anchor at the placewhere it is most liable to be weak.-

ably has a length sufiicient to pass through the several parts which goto make up the frame and in this way act not only to secure the anchorin place but to tie the struc- 7 tural parts parts to each other,' andto the an chor. In order'to defeat any tendency of the anchor to-turnabout the single bolt as a pivot,'the disclosure features one or morefacing flanges co acting with the main plate 30 to form an anglestructureand in its engagement with the mounting supporting structure todefeat'any tendency of the anchor to rotate aboutthe bolt.

Various other objects and advantages of-ss the invention will be inpartobvious from an inspection of the accompanyingdrawing and in part willbe more fully'set forth in the following particular description of oneform of mechanism embodying the inso vention, and the invention alsoconsists" in certain new and novel features of construction' andcombination of parts hereinafter set forth and claimed. V 1

' In the accompanying drawing:

Fig. 1 is a view partly in horizontal section throughthe part of aconventional form of window frame adjacent the window guides,'showing apreferred embodiment of theinvention mounted thereon; i n

Fig. 2 is a plan view looking down upon the anchor shown in Fig. 1 withthe bolt element removed; and

Fig. 3 is a view in front elevation of the anchor looking at the samefrom the right side of Fig. 1.

In the drawing and first referring to the,

lation of the anchor herein featured and afterwards replaced to of theframe.

Referring particularly to the anchor feature of the disclosure there isillustrated a one piece integral casting comprising essen tially a mainplate 17 which is relatively wide as shown in Fig. 2 to obtain therequisite area of engagement with the face 18 ofthe outer supportingframe part or member 12. In the illustrated showing this plate 17. isflat to fit the flat face 18 which constitutes the majority of suchfaces in conventional window frame constructions. In some limitednumberof cases the face 18 is preserve the finish not flat but is curved indifferent ways and it is within the scope of this disclosure to .designthe plate 17 so as to conform to the configuration of the surface 18with which it engages.

It is a feature of this disclosure. that the anchor is secured in placemainly by a single fastening bolt and to accommodate this bolt the plate17 is provided with a non-circular bolt hole 19. A long bolt 20 has anoncircular head portion 21 fitted into the hole 19 so as to preventrotarymovement between the bolt and the anchor when the bolt nut 22 isturned on the oppositeexposed end 23 of the bolt. The bolt extendsthrough the several parts 12, 13, 14 and 15 and acts not only to holdthe plate 19 in firm engagement with the surface 18 but also acts tosecure these frame parts together. In such constructions, the nut 22 isusually accessible without inutilating or dismantling any part of theframe structure and the long bolt not only adds structural material tothe anchor :itself but braces the anchor in a direction at right anglesto the plane of the plate 17. The outer edge of plate 17 is shown to bestraight as indicated at 24 and depending integrally from this plate 17is a pair of face flanges 25 and 26 extending at right angles to theplate 17 and coacting therewith to form an angle member asviewed in sideelevation in Fig. 1. The

face 27 and accordingly the flanges in the device illustrated are eachprovided with a .screw hole 28 into which may be inserted wood screws 29passed therethrough and into the supporting member 12 in oflfsetrelation on opposite sides of the bolt 20.

Extending outwardly fro a the main plate 17 at its straight edge 24- isa harness engaging post 29 pro iecting integrally from the top of theplate 17 and from the portion thereof between the flanges 25 and 26. Thepost is somewhat curved and terminates at its outer end in a square head30. The post is gradually increased in cross sectional area from itsmid-length towards the main plate 17 and rounds into this plate asindicated at 31, 32 and 33 to form maximum strength at the end attachedto the plate. The outer side of the post is concaved as shown at 35 androunds from the head 30 into the. plane containing the flanges 25 and26. In order to lighten the structure at a point where material is notneeded it is suggested that the flanges 25 and 26 be of no greater widththan is necessary to accommodate the screws and thus a space 34 will-beleft in the facing The anchor is mounted in place by removing the facingstrip 16 and drilling a bolt hole through the parts of the casing wherethe anchor is to be located. The anchor is then disposed in positionwith bolt hole 19 in alignment with the drilled bolt hole and with theflanges engaging the outer face 27 of the support. A bolt 20 of theproper length is then passed through the hole 19 and its nut 22 drawn upand tightened until the parts are rigidly secured in place after whichstrip 16 may be replaced and the device readyfor use. In those caseswhere it is desired to pass screws 29 through the face flanges suchscrews may be turned into place thus providing additional security tothe structure as a whole. V

It is within the scope of the disclosure to omit the recess 34 betweenthe flanges 25 and 26 and to use a. single flange instead of the twoflange structure illustrated. It is also within the scope of thedisclosure to provi to two spaced apart posts in place of the singlepost illustrated following a known construction in this respect. 7

By means of a deyice of the type disclosed there is provided apositive,secure connection between an anchoring device and a support even wherethe supportis made up of structural elements which would ordinarily havea tendency to separate when strains were placed upon the anchor. Theanchor can be mounted in position without materially mutilating thesupporting structure and in fact the fastening means are limited to asingle bolt which can be supplied of any requisite length to fit thestructure to which the anchor is attached. As these bolts are standardarticles it is simply necessary in order to attain the advantages hereinoutlined to provide the anchor in the design illustrated and which canbe conveniently formed as a cast ing together with a proper lengthcarriage bolt. Inthis way, an anchor can be provided which can beaccommodated to fit any size frame.

The concaved curved inner side of the post as it merges into the planecontaining the flanges 25, 26 facilitates a quick engagement of the postby the usual attaching clip forming part of the window cleaners safetyharness'and thus ease and positiveness of a quick engagement is assertedby the forwardly projecting disposition of the post head to the outsideof and beyond the planes of the adjacent attaching parts, defined by thesurfaces 18 and 27.
